OK, I can solve that....

What, that's not a joke.
Compound Spiral, huh?

Compound spirals. Well, That's a first for me.
I'll take that Kriek now, please.
All we need now is some unequal tangent curves.
Oh, we have those, too?
Great, can I meet the designer.
I'd like to "thank" him personally for his nice design.
I guess I'll be busy this weekend figuring this out.
Both images, may give you a "headache", but I prefer the first.
Sounds like exit/entrance ramps here in North Carolina!!
I dunno...ASSUMING that the spirals are Searles Spirals (w/ proper documentation), should be a piece of cake. Otherwise, I don't have a clue.

I've always had the hardest time with spirals. The radius to infinity always got me. What is the best reference material for trying to understand the geometry of a spiral? Anybody know?
